Drill a pilot hole, cut threads, and fasten in one motion with these metric-threaded screws. They're self-drilling, meaning they have a pointed tip that forms a pilot hole as they enter your material. As they turn, they also cut their own reusable threads, so you don’t need to drill and tap a hole first. Designed for fastening metal to metal, these screws are often used to install ducts and other assemblies where you can only access one side. The rounded head gives your project a finished look. Made of steel, they’re strong and wear resistant. They’re also plated with zinc to protect the steel from rust and extend the life of the screws. They meet ISO and DIN dimensional standards.
